x86/voyager: fix missing cpu_index initialisation
Impact: fix /proc/cpuinfo output on x86/Voyager Ever since | commit 92cb7612aee39642d109b8d935ad265e602c0563 | Author: Mike Travis <travis@sgi.com> | Date: Fri Oct 19 20:35:04 2007 +0200 | | x86: convert cpuinfo_x86 array to a per_cpu array We've had an extra field in cpuinfo_x86 which is cpu_index. Unfortunately, voyager has never initialised this, although the only noticeable impact seems to be that /proc/cpuinfo shows all zeros for the processor ids. Anyway, fix this by initialising the boot CPU properly and setting the index when the secondaries update.
